To find:

The number.

Solution:

17 less than four times a number is 11, then the number is 7.

We can solve the above mathematical problem using the following mathematical approach.

Let the required number be 'x'.

According to the question, four times the required number is 4x. Now, 17 less than four times the required number can be written as:

$4x - 17 = 11\\\\4x = 28\\\\x = 7.$

Therefore, the required number is 7.
